Radioimmunoassay for human prothrombin.
I describe a radioimmunoassay for human prothrombin, with use of a double-antibody technique. Antiserum raised in rabbits was absorbed with Al(OH)3 and heated to 56 degrees C for 30 min. 125I-labeled prothrombin retaining more than 90% of its biological activity was prepared by the iodine monochloride method. The mean concentration of prothrombin in plasma of 12 normal individuals was 100 +/- 2...
متن کاملHomologous radioimmunoassay of human osteocalcin.
Osteocalcin or bone gamma-glutamic acid-containing protein (GLA protein) was isolated from human bone and used to develop a homologous radioimmunoassay of human osteocalcin. The effect of age on serum osteocalcin was studied in 380 normal children and adolescents and 330 normal adults. The mean (+/- SD) values in adults were higher in men [25 +/- 5 micrograms/L (4.3 +/- 0.8 nmol/L)] than in pre...
متن کاملRadioimmunoassay of Human Plasma Thyrotropin.
Many pituitary hormones possess partial or complete immunological species specificity. Earlier reports suggested that thyrotropin (TSH) did not have such specificity since the biological activity of human pituitary or plasma TSH could be neutralized by antisera to bovine TSH in doses similar to that which blocked the biological activity of bovine TSH (2, 3). However, recent studies have shown t...
متن کاملRadioimmunoassay of human serum thyrotrophin.
The double antibody radioimmunoassay of serum thyroid-stimulating hormone (TSH) allows measurement of circulating levels of the hormone in most normal subjects. The serum TSH level in normal subjects is 1.6 +/- 0.8muU/ml. Patients with non-toxic goitre and acromegaly have normal TSH levels. Values are always raised in hypothyroid patients (with primary thyroid disease) and are significantly low...
متن کاملSecreted Human Neutrophil Collagenase 5647
Collagenase in human neutrophils is found within intracellular granules which can be stimulated to be secreted with phorbol myristic acetate. This extracellular secreted form of neutrophil collagenase was isolated by immunoaffinity chromatography using a monoclonal antibody previously shown to specifically recognize neutrophil collagenase. The enzyme efficiently bound to this column and was ...
